An amateur radio repeater system consisting of a 70 cm repeater and a 2-meter digipeater and iGate. Coaxial cavity RF filter at 2 meter repeater An amateur radio repeater is an electronic device that receives a weak or low-level amateur radio signal and retransmits it at a higher level or higher power, so that the signal can cover longer ...
The 2-meter amateur radio band is a portion of the VHF radio spectrum that comprises frequencies stretching from 144 MHz to 148 MHz [1] in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) [2] [3] and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and Russia).
Morse code is called the original digital mode. Radio telegraphy, designed for machine-to-machine communication is the direct on / off keying of a continuous wave carrier by Morse code symbols, often called amplitude-shift keying or ASK, may be considered to be an amplitude modulated mode of communications, and is rightfully considered the first digital data mode.
EchoLink using VoIP technology has enabled amateurs to communicate through local Internet-connected repeaters and radio nodes, [21] while IRLP has allowed the linking of repeaters to provide greater coverage area. Automatic link establishment (ALE) has enabled continuous amateur radio networks to operate on the high frequency bands with global ...
The 2 200 metre band is available for use in several countries, and the 2007 World Radiocommunication Conference (WRC-07) recommended it as a worldwide amateur allocation. Before the introduction of the 2 200 metre band in the U.K. in 1998, operation on the even lower frequency of 73 kHz, in the LF time signal band, was allowed from 1996–2003.
FM Repeater on 146.940Mhz (-600Khz) Although there is anecdotal evidence of an amateur radio club in Omaha prior to World War II, The Ak-Sar-Ben Amateur Radio Club (AARC), as it exists today, was started in 1945 and has been affiliated with the American Radio Relay League (ARRL) since that time.

As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz ...
Same band repeaters operate with input and output frequencies in the same frequency band. For example, in US two-way radio, 30–50 MHz is one band and 150–174 MHz is another. A repeater with an input of 33.980 MHz and an output of 46.140 MHz is a same band repeater.
